This has been happening reliably for a couple of Konversation versions, but have only just now got the KDE installation rebuilt with debug enabled to gain a meaningful backtrace.

Hard to reproduce this one as it happens completely randomly.
Only assured thing is that it will definitely crash if left running for more than 24 hours.
Equally likely to happen when Konversation is being used or is left unattended.

Not sure if it's a load problem over time, client connects to 3 different IRC servers and about 15 channels, some channels have over 1000 users.

It does bring the machine to a crawl (idle XP 2800+ CPU w/1GB RAM) for a couple of minutes if there are any significant netsplits, but seems to eventually pull through this (may have been due to having the 'Nickname Watcher' enabled which I have now disabled).

Entire KDE install and Konversation built with the following CFLAGS and CXXFLAGS:
'-O2 -march=athlon-xp -pipe -ggdb'

Thanks!
